To all whom it may concern.-

Be it known that we, JAMES L. BOYLE and HENRY E. BRETT,citizens of theUnited States, both residing at 'Los Angeles, in the county of LosAngeles and State'of California, have invented a-new and useful Machinefor Perforating Cylinders, of which the following is a specification. 1I

This invention relates to machines forperforating cylinders, andparticularly to a machine for punching well-casing," and some of theobjects of the invention are to provide a machine of this generalcharacter which will be comparatively simple and cheap in constructionand at the same time positive and effective in operation.

Another object of theinvention is to produce a machine by the use ofwhich great accuracy as to the size or diameter of the product isattained, together with rapidity of operation, and whereby a betterproduct or article is rendered possible.

It is also an object of this invention to produce a machine whereby bothedges of the material or sheet can be punched simultaneously.

With these and other objects in View the inventionconsists,essentially,in the construction, combination, and arrangementof parts, substantially as more fully described in the followingspecification, and illustrated in the accompanying drawings, formingpart of this application, in which 7 Figure 1 is side elevational viewof a machine embodying the main part of this invention.

Similar characters of reference designate corresponding parts throughoutthe several views.

Referring to the drawings, and particularly to Figs. 1 to 3 thereof, thereference character 1 designates a bed-plate of any suitableconstruction whereon are mounted housings 2 and 3, in the free endwhereof is mounted an eccentric shaft 4, Fig. 17, carrying a gearwheel5, which meshes with a pinion 6 on a shaft 7, journaled in the housing 2and in an arm or bracket 8, said shaft carrying a fly- Fig. 15 is a dewheel 9 and band or pulley wheels 10, adapted to be driven by anysuitable agency.

Formed on or connected with the-upper portion of the housings 2 and 3are guide-plates 11, between which is mounted a cross-head 12, Fig. 20,having T-shapcd ends 13 to receive straps 14, encircling slidingbearings 15, working on the eccentric shaft 4, to impart a reciprocatingmotion to the cross-head, and

removably secured to one edge of the cross-v head is a punch holder orplate 16, carrying punches 17, Figs. and of the drawings.

Movably mounted in the housings 2 and 3 isastake 18, Figs. 1, 2, 3, 4,5, and 6, cut away at one end, as at 19, to receive a support or block20, Fig. 2, which is hinged to the housing 3, as at 21, Fig. 1, so as tofold outwardly, as shown in dotted lines in said figure, and saidsupport is preferably provided with an arm 22, by means of which it isoperated and to prevent the operation of the clutch when the support isdown, as will be hereinafter more fully explained. The stake ispreferably provided with a dovetail channel or way 23, Figs. 2, 3, 4, 5,and 6, to receive the die plate or holder 24, which may be securedtherein by a screw or bolt and which is provided with dies 26, Figs. 6and 16, and the stake is desirably constructed with transverse bores oropenings 27 to permit the discharge of the punched-out metal, as will bereadily understood.

In order to insure the proper alinenlent of the punches 17, a perforatedguide-plate 28 is preferably mounted below the cross-head by means ofbrackets 29, secured to the guideplates 11, Figs. 1, 2, and 3 of thedrawings, and for the purpose of securing the proper adjustment of thearticle to be punched depending stops 30 may be provided.

The hub 32, Figs. 17 and 18, of the gearwheel 5 is preferably providedwith recesses or sockets 33 to receive a key 34, slidably mounted in ahub or sleeve 35, keyed upon the eccentric shaft 4, and said key isforced into the socket 33 of the hub 32 by means of a spring or otherdevice 37, secured upon the housing 2, as shown in Fig. l of thedrawings, and a collar 36 may be mounted outside of the sleeve 35 toretain the key in position and to facilitate the action of theclutch-lever 38, Figs. 1, 2, 3, and 19, fulcrumed in a bracket 39 uponthe housing 2 and preferably constructed with a beveled or inclined face40, Fig. 19, adapted to enter between the head of the key 34 and thecollar 36 to force the former out of engagement with the hub or thegear-wheel 5, thereby stopping the action of the machine, which is onlyin operation when the key 34 is in engagement with the hub of thegear-wheel 5, which latter travels constantly. The free end of the lever38 is movably connected with a link or bar 41, which is in turnconnected with one end of a treadle or foot-lever 42, fnlcrumed at 43 tothe bed-plate of the machine and preferably having the free end thereofdeflected laterally, as at 44, Fig. 2, to be engaged by the arm 22 ofthe support 20 in order that the treadle cannot be depressed and themachine started while the support 20 is out of engagement with the stake18, thereby preventing injury to the machine.

Suitably secured upon the bed-plate is a plate or frame 45, Figs. 3, 4,and 5 of the drawings, having a socket or. bearingv 46 to receive a post47, having an apertured end 48, constructed to receive the intermediatesmooth portion of a right and left threaded screw 49 and to beretainedin position thereon by collars 50, carrying set-screws, while each endof the screw 49 is preferably provided with a hand-wheel 51 to rotatethe screw, or any other suitable means may be employed for that purpose.Mounted upon the screw 49, on each side of said posts 47, are nuts 52,Fig. 11, having trunnions 53, constructed to work in the two-partbearings 54 upon the mold 55 and the clamps 56, respectively,substantially as illustrated in Figs. 2 to 5 of the drawings. By meansof this construction either the mold or the clamp can be easily andrapidly operated and either can be removed and the other substituted inits place with great rapidity, and various sizes of molds and clamps canbe used, with the corresponding changes in the size of thepressure-plate and mandrel, respectively, while utilizing the mainportion of the machine.

A pin tle or fulcrum-shaft 57 may be removably mounted in thebed-platein any suitable manner, and the respective jaws of the mold andclamp will be constructed with an opening through which said shaft 57can be passed, and one of the jaws may be bifurcated to straddle theother jaw,'substantially as illustrated at 58 in Fig. 1 of the drawings.

Referring now particularly to Figs. 2, 3, 7, 8, 9, and 21 of thedrawings, the parts employed in the construction of the inner orinternal section or joint of casing will be specifically described,which parts consist in a mold 55, embracing two substantiallysemicylindrical portions 59, supported and reinforced by ribs 60,extending from a head or plate 61, provided with extensions or arms 62and 63, respectively, the former having an opening for the passage ofthe fulcrum-shaft 57, Fig. 7 of the drawings, and the latter beingbifurcated at 64 and straddling or spanning the arms 62, and formed onor connected with the head 61 are the two-part bearings 54 for thetrunnions of the traveling nuts 52, as before described. In order toprovide for accurate adjustment of the separate parts of the mold 55,the same may be provided with threaded lugs or cars 65 to receivestop-screws 66, which regulate the position of the parts of the moldwhen the latter is closed and which can be set to any desired length, aswill be readily understood. In order to force the section or joint ofeasing tightly against the mold 55 throughout all parts thereof,

there is employed a pressure-plate 67, Figs. 2, 3, 8, and 9 of thedrawings, preferablyembodying a split cylinder 68,desirably flattenedlongitudinally, as at 69, Figs. 8 and 9, and provided with openings toreceive the dies 26, which pass therethrough and through a subjoinedstrip or plate 71, secured upon the interior of the cylinder, and aplurality of curved springs 72 are riveted at one end upon the interiorof the cylinder 68 and are slotted at the other end at 73 to move uponthe guidepins 74 in the cylinder in order to allow for the expansion andcontraction of the latter, and the springs are preferably rigidlyconnected alternately, substantially as shown in Fig. 8 of the drawings.

Having described the parts employed in the construction of an internalsection or joint of easing, the operation of the machine during suchconstruction will now be described and is substantially as follows, towit: After the blank has been out, rolled, and provided with thenecessary longitudinal offset the same is introduced within the machineand encircling and placed on the pressure-plate 67, which has beenpreviously secured in position, so that the openings 70 therein registerwith the dies 26 upon the stake inclosed thereby, whereupon the mold isclosed upon the section. By means of the screw 49, operated by thehand-wheels 51, during which process the pressure-plate 67 forces thesection or joint to be formed outwardly against the mold 55 throughoutall parts of the section or joint, thereby insuring the accuracy of thesize of the section throughout all parts thereof as well as insuring theproper alinement between the holes in the two edges of the joint orsection. After the mold shall have been completely closed the treadle 43is depressed, thereby disengaging the clutchlever 38 from thespring-actuated key 34, allowing the latter to be forced into the nextapproaching recess 33 in the hub of the gear- 'wheel 5, therebyimparting motion to the eccentric shaft 4, which reciprocates thecross-head 12, carrying the punches 17, which latter descending upon theedges of the section or joint perforate the same throughout in oneoperation, and the treadle having been released by the operator theclutchlever 38 descendsand disengages the key 34 upon the completion ofone revolution of the eccentric shaft, thereby stopping the machine. Themold is then opened, as in Fig. 3 of the drawings, by the reverseoperation of the hand-wheels and screw. The section is removed from themachine and is then ready to be finally riveted without any necessityfor taking up and fitting the joint or section thus prepared, as is nowrequired in the manufacture of joints or sections of well-casing, asbefore stated. Thus the great advantage attained from the use of thisinvention will be appreciated by those skilled in the art to which thesame appertains.

When it is desired to form an external joint or section of easing, themold 55 is removed by withdrawing the fulcrum-shaft 57 from the bearings75, Fig. 10, which are bolted upon the bed-plate in slots 76, Fig. 2, inorder to permit the adjustment of the fulcrum shaft 57 within the slot77 in the bed-plate, such adjustment being elfected by means ofadjusting-screws 78, Figs. 1 and 10 of the drawings. After the clamp 56shall have been substituted for the mold 55 and the mandrel 79 shallhave been secured in position upon the stake, as before described, theexternal section or joint of casing, having been previously prepared, issecured in position upon the mandrel, and the operation just describedis repeated. By means of the spring-arms 80 of the clamp the casing ispressed closely upon the mandrel throughout the entire surface thereofand the holes are punched in thecasing with great exactness.

The clamp preferably embodies spring-arms 80, carried bya frame 81,having arms or extensions 82 and 85, respectively, the former having anopening in the end thereof to receive the fulcrumed shaft 57, and thelatter being bifurcated and perforated, as at 84,

, Fig.-12, to receive said shaft and the bridge the arm 82, and theframe 81 also carries the two-part bearings 54, for-the trunnions 53 ofthe traveling'nuts 52 on the screw 49, substantially as beforedescribed.

' The mandrel 79 is preferably provided with an eccentric bore oropening 85in the ends thereof and with a plurality of openings 86 to.permit the passage of the dies when the mandrel isin position upon thestake 18, and the mandrel may be provided with internal reinforcingdisks or ribs 87, if found desirable in practice. 1 v

The operation of this invention will be readily understood by thoseskilled in the art to which it appertains by recourse to the foregoingdescription, whentaken in connection with the accompanyingdrawings, andfur ther explanation thereof will not be required.
